TriWin’s Sink PAD PCB Solutions

As a leading PCB manufacturer, TriWin specializes in delivering advanced Sink PAD PCB solutions. Our thermoelectric separation copper base PCBs are engineered to provide superior thermal management, effectively addressing the heat dissipation challenges inherent in high-power electronic applications.

What is a Thermoelectric Separation Copper Base PCB?

A thermoelectric separation copper substrate features a design where the circuit and thermal layers are on different levels. This structure ensures that the thermal layer directly contacts the heat dissipation area, such as the base of a lamp bead, optimizing heat dissipation and thermal conduction. With thermal conductivity reaching 380-400 W/m.K, it addresses the limitations of traditional copper substrates, significantly enhancing heat transfer and reducing thermal resistance.

Key Features of Sink PAD PCB

• Thermoelectric Separation Design:
  • Zero thermal resistance at the lamp bead interface.
  • Minimizes lamp bead decay, extending its lifespan.
• Enhanced Thermal Performance:
  • High density and exceptional thermal carrying capacity.
  • Superior heat conduction and dissipation with a compact design.
• Compatibility with High-Power Applications:
  • Ideal for single high-power lamp beads, especially COB packages.
  • Achieves maximum light output and thermal efficiency.
• Customizable Surface Treatments:
  • Options include OSP, ENIG, HASL LF, immersion silver, and more.
• Structural Versatility:
  • Supports custom designs, including copper convex/concave blocks and parallel thermal and trace layers.
